This product is terrible. The dye on the strips spreads all over the place, I tested three different products and they all tested the same: one from an alkaline jug, one from well water and one from a fridge. and they were all the same, and I know it's not right. AND IT WILL NOT ALLOW ME TO REFUND AND RECEIVE MY MONEY FOR THIS ITEM. I do NOT advise against purchasing this item.
